A simple implementation of a GCode Parser and CNC in Micropython. The example cnc I built, interfaces with the microcontroller through 2 8-bit shift registers in series using SPI interface. 4 L293D Motor drivers are connected to the shift registers to controll them. This repo includes a Shift register class, LN293D class, GCode Parser class and a CNC class as well. You can customize the CNC based on your particular setup.
